Madbull Ultimate Ball Bearing Spring Guide Version 3


The version 2 ball bearing spring guide features a slightly thinner diameter shaft to accommodate springs of all sorts, making it more forgiving for both the spring and piston to compress.  The spring guide's shaft is built-in with the top bearing plate to allow more rigidity and maximum spring decompression.  As a spring decompresses, the bearings allow full twisting, adding improved rounds-per-second and maximum power.

  • Thinner guide shaft for easy, stress-fee spring compression
  • One piece bearing top plate and guide shaft.
  • Loose bearings for maximum spring twisting.
  • Smooth anodized finish.
  • Machined lightweight CNC aluminum.
